Problems solved by technology

[0003] 1. Secondary pollution: The dynamic desulfurization process must add a certain proportion of water in order to ensure the carbonization of rubber powder due to uneven heating. Water and regeneration agent react under high temperature conditions to produce a large amount of organic gas. The problem of secondary pollution cannot be fundamentally solved
[0004] 2. Poor safety: the current working pressure of the dynamic desulfurization process is 1.6-3.2Mpa and class II pressure vessels are required. Long-term use will cause the tan

Embodiment 1

[0024] The production device of the environmentally friendly recovered rubber includes a stirring device 1, a feeding device 2, a plasticizing device 3 and a cooling device 4 connected in sequence, and is characterized in that: the heating device on the plasticizing device 3 is an electric heating device 5, and the plasticizing device 3 Both the device 3 and the cooling device 4 are equipped with a double-screw conveying device 6, and the double-screw conveying device 6 is controlled synchronously and reversely by two mutually meshing gears; the motors on the feeding device 2, the plasticizing device 3 and the cooling device 4 7 are all connected with the frequency converter 8, and the frequency converter 8 is connected with the computer control system;

[0025] In the production device of environmentally friendly recovered rubber, the plasticized rubber powder is transported through the double screw conveying device 6 in the plasticizing device 3 and the cooling device 4, whic...

Embodiment 2

[0027] Example 2:

[0028] The production method of the above-mentioned environmentally friendly restored rubber is to crush the waste rubber into rubber powder, add a certain proportion of activator and environmentally friendly oil, mix uniformly in the stirring device 1, and transport it into the plasticizing device 3 through the feeding device 2. Heating and plasticizing, cooling in the cooling device 4 to obtain plasticized rubber powder, sending the plasticized rubber powder into the rubber rolling process, kneading, thinning and refining to produce sheets.

[0029] The production method of the environment-friendly recovery rubber, its production steps are as follows:

[0030] Take 16-18 mesh rubber powder, mix for 40-50 minutes, plasticize at 220-240°C, and plasticize for 10-11 minutes for production:

[0031] Step 1, batching mixing: add activator and environment-friendly oil to the rubber powder pulverized to 16~18 purposes, by its weight ratio is rubber powder: activ...

Embodiment 3

[0035] Take 18-20 mesh rubber powder, stir for 50-60 minutes, plasticize at 240-260° C., and plasticize for 11-12 minutes. Others are the same as in Example 1.

Abstract

The invention discloses a process and a device for recycling waste rubber, in particular a device and a method for producing environmentally-friendly revived rubber. The device for producing the environmentally-friendly revived rubber is characterized in that: a heating device arranged on a plasticizing device is an electrical heating device; and two-screw conveyers are arranged in both the plasticizing device and a cooling device. The method for producing the environmentally-friendly revived rubber comprises: crushing the waste rubber into rubber powder, adding an active agent and environmentally-friendly oil into the rubber powder in a certain proportion, uniformly mixing the materials, heating the mixture in the plasticizing device electrically for plasticization, cooling the product of the plasticization to obtain plastic rubber powder, conveying the plastic rubber powder to a rubber rolling process, kneading the plastic rubber powder, and performing thin-pass refining to make rubber sheets. The method and the device for producing the environmentally-friendly revived rubber have the advantages of improving the mixing ratio of the conventional rubber plasticizing process, improving the quality of the revived rubber, effectively solving the problem that the rubber adheres on walls in production and conveying processes, recycling rubber volatile, saving energy and protecting environment.

Description

(1) Technical field [0001] The invention relates to a waste rubber recycling process and its device, in particular to a production device and method of environmentally friendly recovered rubber. (2) Background technology [0002] As an important strategic material, rubber is very important to all countries. my country is a big country that uses rubber, and the amount of waste rubber produced is relatively large. The country has been advocating, encouraging and supporting the production technology of waste rubber reuse and reclaimed rubber. , to solve the shortage of rubber resources in my country. At present, the desulfurization of reclaimed rubber mainly adopts dynamic desulfurization process, and its main disadvantages are as follows: [0003] 1. Secondary pollution: The dynamic desulfurization process must add a certain proportion of water in order to ensure the carbonization of rubber powder due to uneven heating. Water and regeneration agent react under high temperature...
